 # Notes / Bugfixes
 ## Frontend
 - [] support esc to close sidebar
-- [] after an hour(?) of inactivity -> show large popup w/ "maybe old data (ignore) (reload page)" (ignore bc maybe use is actively doing something -> don't throw input away!)
+- [] reload page -> don't throw input away!
 
+## Backend
+- [] variable for kiosk mode (needed especially for header)
+- [] Logbuch form -> can't be submitted if arrival date is set (needed for Nachtrag)
 
 # Nice to have
